As Matt Butland pointed out, there are very fundamental reasons why anything pretending to be x86 will eat batteries for breakfast.
Intel flogged it's XScale division because it had an "epiphany" about what type of market it was targetting. That was discussed on el-reg about six months ago.
"Ultra Low Voltage" is a matter of fabrication technology, not processor architecture, an in order to displace ARM it's
a) got to offer more _effective_ instructions per second, per watt,
b) got to be cheap
c) symbian has to be ported to x86
As for TI DSPs, I suggest you go and have a good look at OLAP, oh look! An ARM core in the middle of a TI die!
Single cycle mutliplier, low branch over-head, SIMD capability... what more do you actually WANT in a DSP?

And just ask the PFY... Archies Rule.
